@mpldr @en4rab Looking at this in more detail, I've yet to be able to find any evidence that this is for a train company. I've found the original job offer, but nothing in it talks of trains.
It also explicitly talks about MS-DOS, so it does sound like a genuine Win 3.11 system. Probably not for a train though.
